Description

Technical Field

[0001] This utility model relates to the field of lighting, and in particular to a lamp holder. Background Technology

[0002] With the widespread application of LEDs as lighting sources, they are gradually replacing traditional tungsten filament bulbs. However, the shapes of LED chips on the market vary greatly. Some are double-pin LED panels, plug-in LED panels, and long-handled LED strips. To match different types of LED lights, manufacturers need to produce many different styles of lamp holders. This further leads to a wide variety of lamp holders circulating in the market, forcing retailers to prepare multiple types of lamp holders to keep up with market demands. Consequently, consumers need to be more careful when purchasing lamp holders to avoid making mistakes.

[0003] In order to streamline the chaotic lamp holder market, this utility model proposes a new lamp holder solution that is compatible with multiple types of LED light-emitting elements.

[0004] At the same time, existing LED light heads cannot be completely sealed and waterproofed, and even with waterproof lamp covers, the waterproofing effect is not good. Utility Model Content

[0005] This utility model provides a lamp holder to address the problems of inconsistent LED chip structures in the market, leading to product incompatibility and inadequate waterproofing. To achieve the above objectives, this utility model adopts the following technical solution: A lamp holder includes: a lamp holder housing made of elastic insulating rubber or elastic insulating plastic; an insulating base is provided inside the lamp holder housing; two integrally cylindrical conductor contacts are provided on the insulating base, one end of each contact being open and the open end being exposed relative to the insulating base; the insulating base is also provided with a non-penetrating mounting hole; The outer contour of the contact and the inner contour of the mounting hole intersect in the direction of the mounting hole opening.

[0006] Furthermore, the mounting hole has a "T" shaped structure.

[0007] Furthermore, the two contacts include a first contact and a second contact; the first contact and the second contact are respectively connected to the live wire and the neutral wire of the power grid via a conductor.

[0008] Furthermore, a protruding positioning device is also fixed on the insulating base.

[0009] Furthermore, the positioning device is a positioning post.

[0010] Furthermore, the cylindrical cross-sectional area of ​​the contact gradually decreases from the exposed end to the other end.

[0011] Furthermore, the exposed portion of the contact is a ring-shaped cylindrical structure, with the inner diameter of the ring at the open end being the largest, and the inner diameter gradually decreasing from the open end to the other end of the contact.

[0012] Furthermore, the inner wall of the lamp holder housing is provided with mounting threads and a skirt from the inside to the outside; the insulating base is surrounded by an annular sealing ring with an outer diameter smaller than the mounting threads.

[0013] Furthermore, the skirt is a single layer of elastic rubber or elastic plastic, and the skirt and the lamp holder housing are integrally formed.

[0014] Furthermore, the cross-section of the sealing groove is U-shaped, and the bottom surface of the U-shaped sealing groove is an annular plane.

[0015] Furthermore, the sealing ring has a circular structure, with one end open to form an open end, and the other end fixedly and closedly connected to the lamp holder housing to form a closed end; the outer diameter of the sealing ring gradually increases from the open end to the closed end.

[0016] Furthermore, the outer surface of the opening portion of the lamp holder housing is provided with a groove, which matches the locking pin of the lamp cover.

[0017] Compared with the prior art, this utility model has the following beneficial effects: It fully utilizes the cylindrical structure of the contact. When a double-pin lamp board needs to be installed, the double pins are inserted into the contact for fixation, thus fixing and conducting the LED beads. When a plug-in lamp board needs to be installed, the two hollow holes on the plug-in board can directly penetrate the outer surface of the pins, and the spring pieces around the hollow holes will press against the contact points, thus fixing and conducting the LED beads. When a long-handled light strip needs to be installed, the copper sheet of the long-handled light strip is inserted into the mounting hole, and the lever principle is used to press the copper sheet of the long-handled light strip against the outer surface of the contact points, thus fixing and conducting the LED beads.

[0018] This invention also features multi-level sealing and waterproofing. The outer contour of the sealing ring fits perfectly into the inner wall of the lampshade opening, achieving a complete seal through compression using the force of the mounting threads. Simultaneously, the skirt of the lamp holder housing is also made of elastic material. As the lampshade is gradually tightened onto the mounting threads, the elasticity of the skirt adheres tightly to the outer surface of the lampshade, forming a waterproof sealing layer with the skirt tightly pressed against the outer surface of the lampshade.

[0021] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a lamp holder is disclosed, including a lamp holder housing 1 made of elastic insulating rubber or elastic insulating plastic, the lamp holder housing 1 being entirely of elastic insulating material; an insulating base 3 is provided inside the lamp holder housing 1; two integrally cylindrical conductor contacts are provided on the insulating base 3, one end of each contact being open and exposed relative to the insulating base 3. In this design, the cylindrical structure is an annular cylindrical structure, but it can also be an elliptical cylindrical structure, etc. Figure 1 As shown, the two contacts include a first contact 41 and a second contact 42; the first contact 41 and the second contact 42 are respectively connected to the live wire and neutral wire of the power grid via wires. To ensure a more secure connection and a more stable circuit, the cylindrical cross-sectional area of ​​the contacts gradually decreases from the exposed end to the other end. Specifically, the exposed portion of the contact is an annular cylindrical structure, with the inner diameter of the annulus at the open end being the largest, and gradually decreasing from the open end to the other end of the contact. This gradually changing inner diameter creates a taper, which facilitates both fixation and conductivity. The insulating base 3 is also provided with a non-penetrating mounting hole 5, such as... Figure 2 As shown, the mounting hole 5 has a "T" shape. The "T" shape is designed to accommodate the chip on the long-handled light strip, and also prevents the user from inserting the LED chip electrodes backwards. The outer contour of the contact and the inner contour of the mounting hole 5 intersect in the opening direction of the mounting hole 5. To ensure proper insertion of the plug-in type light board, a protruding positioning device is fixed on the insulating base 3. Specifically, the positioning device is a positioning post 6. Because the positioning post 6, the first contact 41, and the second contact 42 are arranged in a triangle, if the plug-in type light board is inserted incorrectly, it will inevitably fail to connect correctly due to the positioning post 6, thus preventing the LED chip from being damaged by voltage due to incorrect insertion.

[0023] The lamp holder of this utility model still needs further waterproof sealing, such as... Figure 1 As shown, the inner wall of the lamp holder housing 1 is provided with mounting threads 12 and a skirt 11 from the inside to the outside; the insulating base 3 is surrounded by an annular sealing ring 13 with an outer diameter smaller than the mounting threads 12. The skirt 11 is a single layer of elastic rubber or elastic plastic, and the skirt 11 and the lamp holder housing 1 are integrally formed. When the gourd-shaped lampshade is installed onto the mounting threads 13, the edge of the lampshade will squeeze the sealing ring 13, allowing the sealing ring 13 to completely maintain a waterproof seal. At the same time, the continuous tightening of the mounting threads 12 will cause the skirt 11 to gradually enlarge along the gourd-shaped lampshade, and the elasticity of the enlarged skirt 11 will further achieve a waterproof seal.

[0024] For an open lampshade with a structure similar to a horn shape, the lampshade can be directly fitted onto the groove 15. Specifically, the outer surface of the opening of the lamp head housing 1 is provided with a groove 15, which matches the locking pin of the lampshade.

[0025] Working principle: The three types of LED lights in this invention are based on their own characteristics and contact, fixation and conduction with the first contact 41 and the second contact 42. The first contact 41 and the second contact 42 are directly connected to the live wire and neutral wire of the power grid through wires passing through the wire hole 2, respectively.

[0026] Specifically, this utility model fully utilizes the cylindrical structure of the contact. When installing a double-pin lamp board, the double pins are inserted into the contact for fixation, achieving both fixing and conduction of the LED beads. When installing a plug-in lamp board, the two perforated holes on the plug-in board can directly penetrate the outer surface of the pins, and the spring contacts around the perforated holes will press against the contacts, achieving both fixing and conduction of the LED beads. When installing a long-handled light strip, the copper sheet of the long-handled light strip is inserted into the mounting hole, and the lever principle is used to press the copper sheet of the long-handled light strip against the outer surface of the contact, achieving both fixing and conduction of the LED beads. Therefore, this application fully utilizes the structure of the contact, enabling the fixing and conduction of three types of LED lights.

[0027] At the same time, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model also features a three-level waterproof sealing structure. The working principle of the three-level waterproofing is as follows: Under the action of the mounting thread 12, as the external thread of the lampshade 7 mates with the mounting thread 12, the skirt 11, made of elastic plastic or elastic rubber material, expands continuously with the changing arc of the lampshade 7, creating tension. This tension causes the inner wall of the skirt 11 to fit tightly against the outer wall of the lampshade 7, meaning the skirt 11, through its own expansion, adheres tightly to the outer surface of the lampshade, forming the first layer of waterproofing. The port contour 71 of the lampshade directly contacts the bottom surface of the "U" of the sealing groove 14, achieving the second layer of waterproof sealing under the force of the mounting thread 12. To ensure the best effect of the second waterproof sealing, the bottom surface of the sealing groove 14 is an annular plane, which directly contacts the port contour of the lampshade 7, maintaining a seal with pressure. Simultaneously, under the force of the installation thread 12, the inner wall 72 of the lampshade 7 port will be engaged with the sealing ring 13 with an inclined angle. The structure of the sealing ring 13 is similar to a cone, allowing the outer wall of the sealing ring 13 and the inner wall 72 of the lampshade 7 port to fit tightly together, forming a third layer of waterproof sealing. Specifically, the sealing ring 13 has a circular structure, with one end open to form an open end, and the other end fixedly and closedly connected to the lamp holder housing 1 to form a closed end. The outer diameter of the sealing ring 13 gradually increases from the open end to the closed end, and the gradually increasing outer diameter helps to completely seal the opening of the lampshade 7. Through three layers of waterproof sealing, the purpose of waterproofing the lampshade is finally achieved.
